Vehicle network with interrupted shared access bus
First Claim
Patent Images
1. A method of incorporating a feature into a shared-access bus architecture comprising the steps of:
- isolating a device from the shared-access bus architecture;
coupling the device to a switch fabric;
providing a feature device for enabling the feature;
coupling the feature device to the switch fabric; and
controlling communication of information between the device and the feature device via the switch fabric.

Abstract
A vehicle network architecture includes an interrupted shared-access bus and a switch fabric incorporated therein at the point of interruption. The switch fabric permits incorporation of a feature or device into the shared access bus architecture without modification or revisions of the shared access bus protocol or legacy devices.
